Besides introducing a whole new batch of Push-Pogopins (and their measurements) into the 'misc' category, we've just introduced our 'D2' Germanium Diode. This diode is pretty good - better than the 1N270 and 1N34 types, with a voltage dropout of only 0.36V at 50mA! We're not exactly sure what type it is, but since we […]

Last week we beefed up the Ardweeny with the Multipack, and this week we're turning out attention to the Arduino. We've just released the CMDR (Compact Motor Driver) Shield, which lets you bi-directionally drive two gear motors or a single stepper motor, read 6 analog sensors, and control up to 8 servos all at the […]

Did you see the lunar eclipse on Monday night? I wish they had it rescheduled for Sunday afternoon, so all of us night-owls-who-have-to-get-up-early could watch that. But noooOOoOO. But at least the internet will save us. At least from information deficit. Laser Cut Helical Springs I wonder if zigzag helical springs can still travel down […]

Actually, it's been done, but not this nicely. Those guys at Ecole Polytechnique Fédérale de Lausanne (EPFL) have a nice report on their "microglider" project. They do some fine work! Bah. That picture is too small! Let's look at a BIG one! Ooo! And they have more big pictures here! This one is nice - […]
